Package: sparsestep Version: 1.0.1 Date: 2021-01-10 Title: SparseStep Regression Authors@R: c(person("Gertjan", "van den Burg", role=c("aut", "cre"), email="gertjanvandenburg@gmail.com"), person("Patrick", "Groenen", email="groenen@ese.eur.nl", role="ctb"), person("Andreas", "Alfons", email="alfons@ese.eur.nl", role="ctb")) Description: Implements the SparseStep model for solving regression problems with a sparsity constraint on the parameters. The SparseStep regression model was proposed in Van den Burg, Groenen, and Alfons (2017) . In the model, a regularization term is added to the regression problem which approximates the counting norm of the parameters. By iteratively improving the approximation a sparse solution to the regression problem can be obtained. In this package both the standard SparseStep algorithm is implemented as well as a path algorithm which uses golden section search to determine solutions with different values for the regularization parameter.
